aerosols

Hello everyone, I am trying to run WRF solar (WRF version 4.5) taking into account both direct effects of aerosols thanks to CAMS AOD forecasts and indirect ones using water- and ice-friendly aerosols climatology. I have difficulty activating Thompson aerosol-aware parametrization. Everything...

Hi team, I'm looking for resources on how to inject aerosols of a known composition, CCN behavior, and INP behavior into the WRF-Chem to understand the ACI effects of the released aerosols. Is this conducted as something similar to a tracer quantity, or specifically, what all goes into locating...

Hi all, I will be using the aerosol-aware Thompson scheme to look at the sensitivity of clouds to initial CCN and INP concentrations. I was wondering if I am supposed to change the content of the QNWFA_QNIFA_QNBCA_SIGMA_MONTHLY.dat file to do that. If not, I would appreciate your insights on...

Hello, I wish to use WRF-Chem V4.5.1 together with the CBMZ/MOSAIC chemistry option on two nested domains over Eastern Europe for a simulation of 54 hours. However, the run stops after some time whenever I select aerchem_onoff = 1 for my domains in order to include aerosol chemistry. The run...

Dear everyone, I met a problem: I am running WRF-chem V3.9, and when I finished running the first real.exe, I found that the generated wrfinput and wrfbdy files are missing a lot of variables, and the aerosol variables that I am concerned about are not there at all (as in Figure 1 in the...

Dear all, I have been stacked on this problem for half a year, I am gateful that if someone could help me solve this problem. My situation is that the WRF-Chem V3.9.1.1 is always stopped after photolysis driver (rsl.error.000?) and it also happens in latest version (WRF-Chem V4.5.1). The stop...

Hi everyone, I am trying to increase water friendly aerosol number concentration over the Great Barrier Reef to test the sensitivity of clouds to aerosol loading. The Thompson Aerosol Aware microphysical scheme is applied, and auxiliary aerosol climatology is used...

Dear all, I have a small query regarding the computation of the perturbation in atmospheric variables due to aerosol-cloud interaction (ACI) using the WRF-Chem model. In the case of aerosol-radiation interaction (ARI), the perturbation in atmospheric parameters can be computed by taking the...

Hi all, I am trying to run the aerosol-aware version with mp_physics = 28 option under WRF V4.4. Following all the instructions, the metgrid.exe ran well after adding the following line: &metgrid constants_name = 'QNWFA_QNIFA_QNBCA_SIGMA_MONTHLY.dat' The B_WIF_*、 I_WIF_* 、 W_WIF_* have been...

I've used mp_physics=28 in previous versions of WRF with no problem, but now I'm getting errors from real with V4.4. Namelist.input contains: wif_input_opt = 1, num_wif_levels = 30, mp_physics = 28, 28, 28, use_aero_icbc...

Hi, I am curious if there are prescribed aerosols value in WRF model (not WRF-Chem or WRF-ACI). If yes, where I could find those species and values I am thankful for any idea about this. Thanks. Lily
